During my studies I developed a passion for technology. From publishing my first apps in high school to establishing the Finance and Technology society at university, I have sought to engage with this field and combine it with my other areas of interest. This led me to pursue Warwick\'s MSc Business Analytics, for which I secured a 25% scholarship. Whilst studying data science and pursuing iOS development projects alongside, I realised that I don’t just enjoy programming. I enjoy designing systems and building applications, jumping across levels of abstraction to implement algorithms and relish the creative process behind software development in general. This epiphany decisively confirmed my desire to become a Software Engineer. I have worked with multiple technologies with my main focus being iOS development and data science applications. Building multiple and releasing multiple apps for clients and myself. I ventured into web development, learning HTML, CSS, JavaScript, Django and React.
